This Averest Modern Power System Protective Relaying training seminar has been designed to provide a clear and perfect understanding of power system protection schemes and devices including protection relays, fuses, circuit breakers, and other protective devices. In modern power systems, nowadays, protection systems play a significant role in efficiently running plant operations, utility switching, industry load transfer, maintenance programs, and investment policies. The outcome is to minimize system outages and to keep the maintenance and repair costs at reasonable prices. With the advancement of technology, now there is a need for many system operators, electrical engineers (at all levels of proficiency), asset engineers, and project engineers to learn more about the power system protection concepts, logic, and applications to acceptable levels.
